Method for controlling termite

Abstract

Termites can be controlled by applying an effective amount of N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6-difluorobenzoyl)urea supported on cellulose.

1. A method for controlling termite which comprises applying an effective amount for controlling termites of N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6-difluorobenzoyl)urea supported on cellulose to termite tunnel, lumber damaged by termites or a locus termites inhabit. 
     
     
       2. A method for controlling termites according to  claim 1 , which comprises applying 0.01 g to 100 g per 1 m 2  of N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6-difluorobenzoyl)urea to lumber damaged by termites or a locus termites inhabit. 
     
     
       3. A method for controlling termites according to  claim 1 , which comprises applying 0.01 to 1000 g of N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6-difluorobenzoyl)urea to a termite tunnel. 
     
     
       4. A termite-controlling agent which comprises N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6-difluorobenzoyl)urea as an active ingredient supported on a cellulose sheet. 
     
     
       5. A termite-controlling agent according to  claim 4 , which comprises 0.1 mg to 100 g of N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6- difluorobenzoyl)urea per 1 m 2  of cellulose paper. 
     
     
       6. A termite-controlling agent which comprises N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6-difluorobenzoyl)urea as an active ingredient supported on wood chips or wood powder. 
     
     
       7. A termite-controlling agent which comprises N-[2-chloro-3,5-bis(trifluoromethyl)phenyl]-N′-(2,6-difluorobenzoyl)urea as an active ingredient and cellulose powder.
